I did not have that type of experience with the VA for over 30 years
We have a few family friends that work for the VA, including a hospital administrator that is a dear friend.
My concern comes from folks thinking that the private sector has better employees and provide better services.
Something came up in conversation today at work that made me think of this thread and some things that you posted.
I think one of my arguments against a single-payer system also holds true with a monopoly in the private sector. Let's use Walmart as an example. Walmart comes into a market or segment (say grocery) and uses its tremendous buying power to price out the competition. Then when any meaningful competition is reduced or even eliminated, prices can, and often do, go up and services go down.
The difference is in the private sector there can be government intervention because of anti-monopoly laws and/or competition including technology advances. With the public sector there seems to never be any corrective action when a similar situation occurs and the solution to eroding efficiencies and services and the solution seems to be to throw more monies and resources at the situation.
So in theory I am against similar situations in both the public and private sectors. I like healthy competition in both instances. I hope this explanation helps clarify my positions.
